蕃茄较耐低温,冬季在北纬40℃地区,如果在保温较好的日光温室内,均可以进行越冬栽培,但冬季番茄生产风险较大,容易由于遭受冻害而使生产毁于一旦。因此。日光温室增温保温,特别对北方气候严寒地区.这项技术则更加重要。这也是番茄冬季生产成功的关键。目光温室冬季保温的具体措施是: 1.要选择合理的温室结构,并保持良好的密封 Tomatoes are more resistant to low temperatures. In winter, at 40 ° C in the north, if the plants are overwintering in a well-conservatory solar greenhouse, the risk of tomato production in winter is greater and the production is easily destroyed as a result of frost damage. therefore. Solar greenhouse warming, especially for the cold northern climate, the technology is even more important. This is also the key to the success of winter tomato production. The specific measures of winter greenhouse insulation look: 1. To choose a reasonable greenhouse structure, and maintain a good seal
